Thread: How to get two separate map files on SD working on some older nüvi GPS models

easy rider, your device support only one gmapsupp.img file with max size 4GB on micro SD (size of microSD may be up to 32 Gb and microSD must have HC specification only).

You are absolutely right- I had to start from the very beginning, what I did, to grind down all knowledges that I miss, but, somehow, I came across an ocean of somewhat controversial and vague info, which I can not select and systemize to the best of my ability/ if any/, having grain, not the straw to avoid situation like this, ie, to make bricks without straw I tried to ask simple questions, awaitng simple answers to match my simplicity,anyhow. Here, by your courtesy, I learned more than months dedicated to this matter.

Catymag, thank you for reverting. As for the link,you posted, I already followed in advance yesterday, as if I knew for the gentle and helpful reproach, that was in store for me in Giomen's one, I'm thankfully reading now :-)

Once more, thank you all guys, for your assistance and friendly attitude to a total newbie.
